Dashboard Templates to Monitor Google’s New Account-Level Placement Exclusions

Hook: Stop losing conversions to hidden exclusions — monitor account-level placement exclusions in real time

Google's January 2026 launch of account-level placement exclusions fixed a long-standing operational gap: one setting to block placements across Performance Max, Demand Gen, YouTube, and Display. But that control introduces a new operational risk — when exclusions are added or misapplied at the account level, impressions, clicks, and conversions can drop suddenly across dozens of campaigns with limited visibility. This guide gives you pre-built dashboard templates and ready-to-deploy alert rules to monitor where placement exclusions are affecting campaign health, detect anomalies, and restore growth quickly.

Executive summary — what to deploy first (inverted pyramid)

• Immediate action: Deploy the Account Exclusions Overview dashboard to surface sudden drops in impressions, CTR, spend, and conversions within the first 24 hours of an exclusion change.
• Monitoring: Use the Placement Leakage dashboard to map excluded domains/apps to lost impressions and conversions by campaign and device.
• Alerting: Activate anomaly rules that combine relative drops (percent change) and statistical deviation (z-score or EWMA) to cut false positives.
• Data flow: Prefer Google Ads API -> BigQuery export + hourly sync for reliable, account-level visibility and long-term analysis.

Why account-level placement exclusions matter in 2026

Google's January 15, 2026 announcement brings centralized control to placement management. This is a response to two converging trends:

• Wider adoption of automation (Performance Max & Demand Gen) in 2024–2025 demanded broader guardrails at scale.
• Privacy-driven measurement shifts (cookieless environments, modeled conversions) made placement-level signals both more valuable and harder to interpret.

“Once a placement is excluded at the account level, Google Ads prevents spend on those websites, apps, or YouTube placements across all eligible campaigns.” — Google Ads, Jan 15, 2026

That centralization reduces setup overhead but increases blast radius. A misapplied exclusion can silently reduce impressions across dozens of campaigns. Your monitoring must evolve from campaign-by-campaign checks to account-wide dashboards and automated anomaly detection.

How account-level exclusions affect campaign health and attribution

Account-level exclusions change supply availability across channels. Expect three primary effects:

1. Impression displacement: Exclusions remove inventory; metrics like impressions and viewable impressions drop. Automation reallocates budgets — often to new placements or formats.
2. Immediate click/conversion impact: Clicks and conversions tied to excluded placements stop. That can cause sudden shifts in CPA and ROAS as the platform reoptimizes.
3. Attribution noise: When conversions are modeled (server-side or aggregated), attribution windows and signals can obscure the true impact of an exclusion for days.

Practical example: if an account excludes a high-volume YouTube placement that historically contributed 15% of monthly conversions, a naive monitoring setup might only see a gradual decline due to attribution delays. A real-time dashboard will show a step drop in impressions and a concurrent rise in CPA within 24 hours.

What to monitor — essential KPIs and signals

Design dashboards around signals that show both direct and indirect effects.

• Account-level KPIs: impressions, clicks, cost, conversions, conversion rate (CVR), CPA, ROAS — segmented by channel (Display, YouTube, Performance Max, Demand Gen).
• Placement-level signals: excluded vs non-excluded placement counts, impressions lost (estimated), top excluded domains/apps by historical conversion value.
• Cohort metrics: 1-day, 7-day, 28-day rolling changes to isolate attribution lags.
• Device & geo splits: Exclusions often disproportionately affect mobile/SVC placements or specific geos.
• Automation flags: sudden bid adjustments, budget reallocation events, or Performance Max asset performance shifts.

Pre-built dashboard templates to deploy (and what each shows)

Below are four production-ready dashboard templates. Each section explains the widgets, data sources, and sample queries you can paste into Looker Studio, Grafana, or a custom app that reads from BigQuery.

1) Account Exclusions Overview (24/7 health check)

Purpose: Fast triage after an account-level exclusion change.

• Widgets: Account-level KPIs (impressions, clicks, cost, conversions, CPA) with 24h vs 7d change badges.
• Trend charts: Hourly impressions and conversions across last 72 hours.
• Exclusion event log: timestamp, user, excluded placement pattern (domain/app/YouTube channel), remark field.
• Heatmap: Campaigns by % impression loss (last 24h vs baseline).

Data model: Google Ads API (GAQL) -> BigQuery hourly load or Google Ads > Analytics 4 export when available.

Sample BigQuery snippet to compute 24h vs baseline % change (pseudo-SQL):

SELECT
  campaign_id,
  SUM(impressions) AS impressions_24h,
  SUM(conversions) AS conv_24h,
  SUM(impressions) / NULLIF(AVG(impressions_7d),0) - 1 AS pct_change_vs_7d
FROM (
  SELECT campaign_id, impressions, conversions, DATE(event_time) AS d
  FROM `project.ads_account_hourly`
  WHERE event_time >= TIMESTAMP_SUB(CURRENT_TIMESTAMP(), INTERVAL 24 HOUR)
) t
LEFT JOIN (
  SELECT campaign_id, AVG(impressions) AS impressions_7d
  FROM `project.ads_account_daily`
  WHERE DATE(event_time) BETWEEN DATE_SUB(CURRENT_DATE(), INTERVAL 30 DAY) AND DATE_SUB(CURRENT_DATE(), INTERVAL 8 DAY)
  GROUP BY campaign_id
) baseline USING(campaign_id)
GROUP BY campaign_id;

2) Placement Leakage dashboard (map exclusions to impact)

Purpose: Identify which excluded placements are responsible for lost reach or conversions.

• Top excluded placements by historical impressions, clicks, conversions, and conversion value.
• Estimated lost impressions: historical impressions for the placement * % of period excluded.
• Placement-to-campaign mapping: which campaigns and creatives targeted the placement previously.

Widget idea: Sankey chart from excluded placement -> campaign -> conversion value (last 30 days pre-exclusion).

Sample GAQL to list placements with historical conversions:

SELECT
  placement_view.resource_name,
  segments.date,
  metrics.impressions,
  metrics.clicks,
  metrics.conversions
FROM placement_view
WHERE segments.date BETWEEN '2025-12-01' AND '2026-01-14'
ORDER BY metrics.conversions DESC
LIMIT 100

3) Campaign Health drill-down

Purpose: See how each campaign rebalanced after exclusions and spot sudden CPA/ROAS regressions.

• Metrics: impression share (IS), lost IS (if available), budget pacing, conversion lift/loss.
• Dimension filters: campaign type (PMax, Display, YouTube), device, bid strategy.
• Chart: conversion velocity (conversions per day) versus spend per day, showing reallocation curves.

4) Anomaly & Alerting dashboard

Purpose: Centralize alerts and investigation paths. Shows active anomalies, their confidence scores, and recommended actions.

• Algorithm outputs: z-score, EWMA deviation, seasonally-adjusted residuals.
• Suggested remediation: rollback exclusion, create exception for high-value placement, whitelist publisher domain.
• Integration points: one-click Playbook links to create a Google Ads change or to run a script that re-evaluates the exclusion.

Alert rules and anomaly detection workflows

Good alerts minimize noise and maximize signal. Use a hybrid approach: relative threshold + statistical anomaly detection + domain-specific rules.

Rule set A — Fast triage (high sensitivity)

• Trigger: >20% drop in account impressions AND >15% drop in conversions within 24 hours.
• Suppress if: exclusion change event exists in the last 6 hours (avoid duplicate alerting).
• Delivery: SMS & Slack to paid-search on-call; auto-open ticket in your incident system.

Rule set B — Robust anomaly detection (lower noise)

• Metric baseline: rolling 28-day median, with day-of-week adjustment.
• Algorithm: compute z-score for hourly impressions and conversions; trigger at z > 3 for 3 consecutive hours OR EWMA drop > 25% vs baseline.
• Enrichment: verify exclusion change via the account-level exclusion log (user + timestamp).
• Delivery: Slack + email; include suggested remediation steps and quick links to the Placement Leakage dashboard.

Sample SQL for EWMA-based anomaly detection (BigQuery)

WITH hourly AS (
  SELECT TIMESTAMP_TRUNC(event_time, HOUR) AS hour, SUM(impressions) AS impressions
  FROM `project.ads_account_hourly`
  WHERE event_time >= TIMESTAMP_SUB(CURRENT_TIMESTAMP(), INTERVAL 60 DAY)
  GROUP BY hour
), ewma AS (
  SELECT hour, impressions,
  -- alpha set to 0.3 for moderate responsiveness
  EXP(SUM(LOG(1-0.3))) OVER (ORDER BY hour) AS dummy
  FROM hourly
)
SELECT hour, impressions,
  -- compute EWMA externally or in your analytics layer; many engines provide it
  FROM hourly
ORDER BY hour DESC LIMIT 100;

Note: implement EWMA in your analytics engine or compute iteratively in a Cloud Function if your SQL flavor lacks windowed exponential functions. For implementation patterns and ops around observability, see Cloud Native Observability.

Alert payload — what to include

• Context: account, affected campaigns, timestamp of exclusion change (if any).
• Key metrics: % change in impressions, conversions, CPA, and estimated lost conversion value.
• Confidence: z-score or anomaly model score.
• Suggested actions: rollback exclusion, whitelist domain for specific campaigns, or escalate to brand-safety team.

Data sources and recommended integration patterns

For high-fidelity monitoring and flexible dashboards, follow this pipeline:

1. Google Ads API (GAQL) hourly export -> BigQuery. Include placement_view, campaign, and change_history tables.
2. Combine with your conversion data source (server-side conversion API or GA4 BigQuery export) to avoid attribution lags.
3. Enrich with publisher metadata (domain, app category) via internal lookup table.
4. Build dashboards in Looker Studio for quick sharing and Grafana/Looker for advanced analytics and alerting. For tools and integration patterns, see top observability tool reviews.

Why BigQuery? It gives you the scale to run cohort analysis and statistical models, host pre-computed hourly aggregates for low-latency dashboards, and store the exclusion change log for audit trails.

Checklist: rollout plan to deploy dashboards and alerts in 7 days

1. Day 1: Connect Google Ads API to your BigQuery project; schedule hourly exports of placement and metrics.
2. Day 2: Import your conversions (server-side or GA4) and create a unified schema for impressions, clicks, conversions.
3. Day 3: Deploy the Account Exclusions Overview in Looker Studio using the pre-built report templates.
4. Day 4: Implement Placement Leakage dashboard and configure Sankey mapping.
5. Day 5: Add anomaly detection logic (z-score and EWMA) as scheduled queries and expose results to dashboard.
6. Day 6: Configure alert rules and integrate with Slack/email/incident systems. See incident playbooks in outage-ready.
7. Day 7: Run a simulated exclusion event to test end-to-end detection and response playbook.

Case study: how a mid-market retailer recovered 18% of conversions in 48 hours

Background: PeakGear (fictional name), a 120-campaign e-commerce account, applied an account-level exclusion list to remove low-quality inventory. Within 24 hours, their overall impressions dropped by 14% and conversions by 18%. The marketing team saw CPA creep and assumed creative fatigue.

Action using the templates:

• Account Exclusions Overview showed a simultaneous timestamped exclusion change by an analyst.
• Placement Leakage dashboard identified three YouTube channels accounting for 12% of historical conversions that the team had accidentally excluded due to a domain-matching rule.
• Alerting dashboard had already fired with a z-score of 4.2 for hourly conversion drops; the on-call analyst received Slack and an auto-created ticket.
• Remediation: the exclusion was rolled back for a single high-performing channel; within 48 hours, impressions and conversions normalized and CPA fell back to baseline.

Result: PeakGear recovered ~18% of lost conversions and avoided a 5% drop in monthly revenue. The postmortem added a whitelist exception for high-ROI publishers to the account-level exclusion playbook.

Advanced strategies & future proofing (2026+)

Next-level monitoring integrates predictive models and privacy-forward signals:

• Predictive impact estimation: Train a model on historical placements to estimate conversion lift/loss before applying an account-level exclusion. Run simulations in BigQuery ML and validate before push.
• Cohort-aware exclusions: Tune exclusions per audience segment instead of one blanket list — e.g., whitelist placements for high-value cohorts. For edge- and cost-aware strategies that intersect with predictive models, see edge-first cost-aware strategies.
• Privacy-aware signal modeling: Use deidentified server-side conversions and aggregated measurement to attribute changes reliably even with stricter signal loss.
• Publisher reputation scoring: Combine third-party fraud and brand-safety feeds with your conversion ROI to rank placements for automated exclusion recommendations. Security and scoring workstreams can borrow practices from deep security reviews like security & access governance.

As measurement evolves in 2026, the accounts that pair centralized exclusions with intelligent monitoring — not manual guesswork — will preserve automation’s efficiency while protecting ROI.

Common pitfalls and how to avoid them

• Avoid relying on daily reports only. Hourly telemetry captures the initial rebalancing window when automation can misallocate budgets.
• Don’t mute exclusion change logs. Always correlate exclusion events with metric shifts before making optimizations.
• Watch for attribution lag. Always compare short-term (24–72h) and medium-term (7–28d) windows to separate immediate impact from modeled conversions.
• Guard against excessive whitelisting. Maintain publisher-level ROI thresholds to avoid reinstating low-quality inventory.

Actionable takeaways

• Deploy the Account Exclusions Overview and Placement Leakage dashboards immediately after enabling account-level exclusions.
• Use a hybrid alerting strategy: simple percent-change rules for speed + statistical anomaly detection for precision.
• Store an immutable exclusion change log in BigQuery to correlate events with performance and support audits. For durable recovery and audit guidance, see cloud recovery best practices.
• Simulate exclusion changes with predictive models before applying broad account-level rules.

Final thoughts and next steps

Account-level placement exclusions are a major productivity win — but only if you pair them with robust monitoring and smart alerts. Use the dashboard templates and alert rules above to reduce time-to-insight, limit revenue leakage, and keep automation working for you.
